NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 689,637, dated December24, 1901.

Application filed August 28, 1901. Serial No. 73,606. (No model.)

To all whom, it may concern:

Be it known that I, ISAAC M. CHANNEL, a citizen of the United States ofAmerica, residing at Duquesne, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in Nut-Locks, of which the following is a specification, reference being hadtherein to the accompanying drawings This invention relates to certainnew and useful improvements in nut-locks, and has for its object theprovision of novel means that will effectually lock the nut to the boltand prevent it fromturning or jarring loose.

The present invention. aims to construct a device of the above-describedcharacter wherein it will not be necessary to change the construction ofeither the bolt or nut and one that may be applied to all standard formsof nuts and bolts.

Another object of the invention is to construct a nut-lock that will beextremely simple in its construction, strong, durable, and comparativelyinexpensive to manufacture.

With the above and other objects in view the invention finally consistsin the novel construction, combination, and arrangement of parts, to behereinafter more particularly described, and specifically pointed out inthe claim.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification,and whereinlike numerals of reference indicate like parts throughout the severalviews,in which- Figure 1 is a side elevation of a bolt and nut providedwith my improved nut-lock. Fig. 2 is a similar View showing the nut-lockin vertical section. Fig. 3'is a front View thereof. Fig. 4 is a sideelevation of a modified form of nut-lock. Fig. 5 is an end view of thesame. Fig. 6 is a side and end detail view of the lock. Fig. 7 is aperspective view of the 1ocking-wedge.

In the drawings the reference-numeral 1 represents the bolt, and 2 thenut, both being of the ordinary and well-known construction.

The reference-numeral 3 represents a casing having a front plate 4,through which the 50 threaded portion of the nut extends. The

casing 3 also carriesan enlarged portion 5, through which thelocking-wedge 6 ext-ends. This locking-wedge has formed on its underface a V-shaped engaging face 7, and the and is provided with a seriesof serrations 11.

The modifed forms of my invention, as illustrated in Figs. 4 and 5 ofthe drawings, show a duplication of the locking wedges and keys, onepair of wedges above and one pair below the nut, as in someconstructions I find it of special advantage to use the device in thismanner. In using two pairs of wedges, one pair on the opposite side fromthe other pair, I form the casing with enlarged portions on oppositesides in order to receive such wedges. In this form the wedges arepassed through parallel and in alinement with one another.

The mode of operating my improved nutlock will be readily apparent fromthe foregoing description and by referring to the accompanying drawings.It will be noted, however, that various changes may be made in thedetails of construction without departing from the general spirit of myinvention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a nut-lock, the combination with a nut and bolt, of a casing carryingan enlarged portion entirely surrounding the peripheral faces of the nutand engaging the said bolt, said enlarged portion having a slot formedtherein and extending entirely therethrough, a lock having a V-shapedgroove on its upper face, and a serrated lower face engaging the threadsof the bolt, said lock secured in said slot, and a wedge-shaped keyhaving a V- shaped lower face and one of its ends split engaging in saidslot with its lower face engaging the upper face of said lock, the saidsplit end being bent in opposite directions to engage said casing whenthe wedge is in positiun, substantially as described.

In testimony whereof I affix my signature in the presence of twowitnesses.

ISAAC M. CHANNEL.
